Abstract

Macroscopic plastic deformation of silicon single crystals has been achieved at RT and 150[degree sign]C under a confining pressure of 5 GPa in a multi-anvil apparatus. TEM observations of a sample deformed at 150[degree sign]C show that the deformation microstructure is built with dislocations with Burgers vector in (1 1 1) planes which are undissociated. They appear as mainly aligned along the screw orientation and <1 1 2> orientations at 30[degree sign] from the Burgers vector. Those features are analysed in the light of perfect dislocation generation in the shuffle set.
